Computer Networks Windowing: The quantity of data segments (in bytes) that the transmitting machine is allowed to send without receiving an acknowledgement for them is called window. Acknowledgments: Non-duplication of data is achieved through positive acknowledgement with re transmission. The sender documents each segment it sends and waits for this acknowledgement before sending the next segment. It starts a timer and retransmits if it expires before an acknowledgement is returned from receiving end. The Transport Layer ( Cont…)
